4. For a quick Moaning Myrtle costume, get a cheap toilet seat and some glasses.

Cheap toilet seats tend to be super lightweight, which is bad if you’re sitting on them but great if you’re wearing them around your neck. Put your hair in pigtails and draw on some tears with eyeliner to really rock the look. Learn more about it here.

7. To get this look from The Shining, all you need is foam core and a toy axe.

8. Turn a bald cap and a purple scarf into Professor Quirrell and Voldemort.

Use your fingers to strip off about half of the pipe cleaner fluff before pushing the bare end into your fabric. Knot the wire end to keep it in place and prevent it from stabbing you. You can also take this process and use it to create other spiky costumes like, say, a porcupine. Go here.
